Tab forming

The process of immediately sealing the gas bag edge of a pouch cell after injection to completely isolate the interior of the cell from the external environment.

The process of inputting positive or negative electrode materials (including active substances, conductive agents, etc.) into a mixing device through a metering system according to the preset ratio.

The process of winding matched positive electrode sheets, negative electrode sheets, separator, and tab materials into a core assembly (winding core) by controlling factors such as equipment speed, tension, dimensions, and alignment.

The process of stretching the aluminum-plastic film to form a punched pit structure using a die.

The process of compacting and shaping the electrode assembly by applying appropriate time and pressure, controlling the thickness of the electrode assembly, and securing the shape of the loosely wound electrode assembly to prevent relative movement of the positive and negative electrode sheets.

In the presence of additional pressure, the process of transmitting high-frequency vibration waves through the welding head and welding seat to two objects to be welded. The contact surfaces of the two objects to be welded rub against each other, allowing molecular diffusion, resulting in a form of welding known as molecular fusion.
